Council OKs Agreement With Township for Church Street Sewer Upgrade

The Zeeland City Council has approved a cost-sharing agreement with Zeeland Township for upgrading sanitary sewer lines that will be built in conjunction with next year’s project to rebuild Church Street from Washington Avenue to Lincoln Avenue.

The council Monday approved the agreement for the estimated $2.4 million project, which would upsize the sanitary line between Washington and the city’s Clean Water Plant from 15 inches to 27 inches.

Based on current cost estimates, the township’s share of the cost would be $1,617,850 while the city would have a $782,150 share, City Manager Tim Klunder said.

“As we typically do when we go into a (street) project, we look at the (underground) utilities to see if they can be improved,” Klunder said. “In this particular case, if it was just the city, only servicing our industrial area, we would have probably went in there and relined (the sewer line).”

“However, what we know is that line services the North Riley campus of Gentex (Corporation), and they continue to see and project significant growth out there, plus other growth in the 425 area. When we analyzed future projections of flow coming down through Church Street, it was recommended that line be increased to 27 inches,” the city manager added.

The city and township have had a sewer service agreement to serve the 425 area, including the North Riley Gentex campus, since 1993.

The city’s share of the project includes an upfront contribution of $500,000, which was the estimated cost of relining the sanitary sewer line if the city chose not to proceed with an upgrade. The remaining cost split is based on the projected flow of sewage going through the Church Street line in 2064. It’s projected that 85 percent of the flow will come from the township and 15 percent from the city at that time, Klunder said.

“We appreciate the township’s receptivity to upsize the Church Street sanitary line while

Church Street will be under reconstruction,” Klunder wrote in a memo to the council. “This agreement is reflective of our mutual desire to have the ability to support growth opportunities in our area while doing so at a time that will bring cost ­efficiencies to this project given the street will be under reconstruction when we upsize the sanitary sewer line.”

For now, the Clean Water Plant has enough capacity to handle the expected increased flow, but the city will have to plan for an ­expansion, possibly around 2035. The plant has a current capacity of 3.5 million gallons per day.

“I’d say 2030, 2031, we’ll probably have to start the design process,” Assistant City Manager Kevin Plockmeyer said. 

The Township Board is expected to act on the cost-sharing agreement with the city at its Oct. 7 meeting, Township Manager Josh Eggleston said.
